Breek Arms BRK4320 Sentinel Caged Flash Hider | .223/5.56

The Breek Arms Sentinel Caged Flash Hider is built to work with the Breek-LOK 3QD quick-detach suppressor attachment system. Made from steel with a nitride finish, the unit disperses and redirects muzzle gases to reduce visible flash and help preserve the shooter’s sight picture in low-light conditions. Its closed-prong caged design eliminates an exposed flash-hider ring and reduces snag risk for a cleaner profile on equipped rifles.
